The laptops are based on the Celeron N2840, with 2GB of RAM. I can't seem to find much in the way of benchmarks; but I suspect that they are surprisingly adequate. What is a bit surprising is that the the N2840 has a quoted tray price of $107, so either Intel is cutting HP one hell of a deal, or I don't even want to know what HP cobbled the rest of the system together from...

I don't think that tray price has much basis in reality. The "$107" N2840 looks, at least on the face, to be not vastly different from the "$86" 1037U. If Biostar can sell a motherboard + 1037U + heatsink + fan for $79.99, it doesn't take much of a stretch to think maybe these prices are just "list" prices with no basis in reality. Biostar is just selling a bare motherboard so there can't be any Microsoft kickbacks or ad revenue.

Tesla is selling $100k cars, while other battery factories make batteries for $100 phones and $500 laptops. Maybe it is too expensive for them to set up a fully renewable process.

Or maybe they lease their facility. A lot of companies do, including mine. There's about a 0% chance of us installing renewable powerinfrastructure like that which would be difficult to take with us when we move out.

What many in the U.S. don't realize is that what we call bribery is SOP in some countries. Not that it makes it right, or legal, but it may be the only way for a company to do business there. I've witnessed this first hand in a couple places, with local government officials who would just not process paperwork unless you "tip" them.

That's a "Facilitating payment" and is actually OK for US companies to pay. A facilitating payment is payment to make someone do something faster or more efficiently, but the person was obligated to do that thing anyway. Good examples are customs clearance, port expediting payments, etc. The official is obligated to release items from customs if all the paperwork is correct. He isn't obligated to do that in a timely fashion, however. The payment just makes his inevitable action happen faster.

When you pay for an action which may not have happened without payment (like a favorable decision) that is when it becomes bribery.

I wonder what the value of American-owned assets nationalized by Castro would be worth today had they never been nationalized. My guess is that it has to be at least Cuba's "cost" or worse.

It'd also be interesting to know the value of the lost productivity imposed by Cuba's communist economics.

There is more to life than worrying about "lost productivity". Capitalism is not the best system of government if you care about happiness, equality, and well-being of the people. It is superior in many ways, but in those areas, Capitalism falls pretty flat.

If you, the reader, has any experience with office politics or politics you know the popular underhanded technique of supporting something while undermining it.

Overhead, corruption, and incompetence are too often used as an excuse; many times it IS simply an underhanded attack by the "supporters." When NYPD spends $60,000 while saying it's going to cost more for only 60 cameras there are people involved who WANT it to be as expensive as possible of a deterrent. A high profile test group like NYPD will get cited all over the nation. Given how badly it is needed and demanded by the public, the costs are going to have to be high to deter widespread common use. Despite how actually cheap it would be - I bet their flash lights cost more... I had a cheap pen camera from china that was in that price range; it didn't last long or store much video but that was 6 years ago.

This is also where greedy capitalism comes in because that is all about how much the market is willing to pay--- and they've got to make sure this is a niche market so it doesn't have to compete with the extremely cheap mainstream market.

Sure, the way public budgets are managed is they take all projected costs (on the high side) then divide them out in ways that makes things like this seem like it's $10,000 a camera -- and one can sometimes spot the traitors because they'll focus on such false estimates.

Now it could be this is a totally honest move by NYPD and their high costs are because they are preparing for a full scale deployment with this just being a testing group. I'm just too cynical to take things at face value... wonder if any reporters exist who can hang around enough to pick up on such things anymore.

Hint- Industrial type equipment designed for daily rough use is expensive. I have a Motorola Pro5150 radio on my desk here which apparently costs about $400 (finding an actual price on this thing isn't easy) depending on which model it is. For a radio. But it is built like a tank, designed very well, and looks a lot like what police departments use. A wearable camera built like this radio costing $1000 each might be expensive, but it wouldn't be absurdly expensive.

The pyramids being made by slave labour is something of a myth. There's not much evidence available for early pyramids, but there's plenty of evidence that later pyramids were made by skilled craftsmen and not slaves.

My business is steam turbines. Complicated machinery with very tight tolerances, requiring great skill to put together. We use 1 or 2 experienced turbine experts per shift and have a cadre of millwrights (gorillas) to do the dirty/boring/mindless/unskilled labor.

We are all indoctrinated in certain things, and those beliefs hang onto people like a religion. The notion that "my" country is the best country in the world, and all other countries are inferior in every way, is a hard one to shake. I saw it clearly on my trip to North Korea- although some people there are just playing along, a lot of people there really believe that their nation is the best on earth. It was like looking in a funhouse mirror at the people who chant "USA USA USA". People have to keep inventing reasons to keep believing their indoctrinations. Any evidence supporting their pre-existing beliefs is held up as fact, and any evidence which doesn't agree with their preconceptions is tossed aside as propaganda, fiction, lies, etc. I have seen this with people all over the world. It sucks to be on the losing end of this kind of attitude however.

Hypersonic missiles are the only weapons that could hit an american supercarrier

Incorrect. There are plenty of ways to take out an aircraft carrier. The most obvious and least defensible way is to torpedo it from a submarine. Other ways clearly exist. You can overwhelm it with a mass attack using aircraft, conventional cruise missiles, torpedo boats, etc. Once a carrier and its very limited escort screen use up their antiaircraft and antimissile ammunition, it is a sitting duck. You can strew mines in front of it. You want to give it a severe nightmare? Just consider what you could do moored in its pathetically poorly defended home base or forward base.

Better keep them away from supercaviataing torpedoes, a carrier's true worst nightmare. Russia has had one since the late 70's. Iran has them too.

http://en.wikipedia.org/wiki/VA-111_Shkval

A supercavitating torpedo is a hail mary weapon or a "you fired first" weapon. Cavitation is noisy and is what anyone firing such a weapon would generally want to avoid. It also blinds the torpedo since there is air in front of it instead of water. So they have to be remotely controlled by wire.

Nothing screams "I'M RIGHT HERE!!! IT WAS ME WHO FIRED THAT TORPEDO!!!" like a supercavitating torpedo. It is little better than a kamikaze attack if used offensively.

Finally, i cant stress this enough: you are an engineer, and the pace should be slow. part of that is in your software. ansys, nastran, and fluent jobs will run for weeks at a time, wiping your ass to make sure your design or part is solid and incapable of immolating a school under normal operational parameters. you can quicken the pace by specifying realistic resources to use before you submit to the simulation cluster, and optimizing your simulations instead of queueing them up, locking your screen, and going off to lunch. monitor your checkpoints for failures in convergence. use the latest software instead of demonizing it. run it multicore, and for god sake stop being retiscent and stubborn about new shit that can help you like simulation timing blocks. and another thing, close the application so your license is returned to the pool and can be used on other projects, most of which yours depends on. now get off my lawn.

Skylab was in very good condition and NASA wanted to use it in conjunction with the shuttle, which was scheduled to be operational before Skylab fell into the atmosphere. The Shuttle was to be used to re-boost it, but two things happened: [1] solar activity was higher than expected (which affects the upper-most part of the atmosphere and increased the atmospheric drag on Skylab) and [2] the shuttle ended-up being too far behind schedule. NASA, realizing that shuttles would not be ready in time, studied launching an unmanned "tug" to dock with and re-boost Skylab so it would still be there on orbit and operational by the time shuttles were ready, but congress in the late 70's was as stupid as today - Congress did not fund this cheap solution, so we ended-up dumping $100 Billion and ten years of construction time into building ISS to get a similar orbital capability (Skylab had 320 cubic meters pressurized volume, that's more than the US part of the ISS). The shuttle could have then flown additions to Skylab (which had a docking adapter for multiple visiting vehicles). An enhanced Skylab would have had no Russian "entanglements", and had its own lifesupport and navigation capabilities.

Skylab was FAR from "worn out" and the damage from the launch was quite managable. The astronauts who closed it out left it ready for re-manning. When Skylab re-entered the atmosphere it did so under remote control from the ground, with its systems fully functioning until they were destroyed by the reentry. READ THE DAMNED REPORTS, which consist of hundreds of paged of excellent details, before misinforming people.

Skylab was put into orbit in one launch. Using the shuttle to lift further components is silly- all it does is justify the shuttle. The shuttle is a Honda Fit compared to the 18-wheeler Saturn 5. Letting Skylab burn up may have been a "waste" but if you can launch more than 1/3 of the current ISS volume (currently at around 837 pressurized cubic meters) with 1 Saturn 5 rocket, an orbiting space station then becomes essentially disposable. Just launch another one.

If they can make this work at a reasonable cost the trucking industry is defiantly a place I’d expect to see it. After all fuel efficiency is one of the biggest factors in whether a trucking company makes money or not. I am not sure a dynamic system such as being described in the article makes that much sense for cars and trucks. Making some sort of prefabricated body panels that have some pattern permanent imprinted it in seems like it would be much cheaper and require less long term maintenance.

Dimples are a place for water to collect. Paint nowadays is pretty good, but any break in the paint on a dimpled car would be a big rust problem really quick. It would be a nightmare to repair after an accident. Even if you think the dimples look good, when the water evaporates it will leave water spots and look terrible.
